IEEE 802.11ad (WiGig) LDPC Decoder

Overview

The WiGig standard (IEEE 802.11ad) delivers data rates of up to 7 Gbit/s and hence outperforms the current IEEE 802.11n standard by more than 10x. It uses the 60 GHz band to enable short range communication and interoperability between a broad set of applications and platforms.

The Creonic WiGig LDPC decoder is designed in particular to deliver highest throughputs in the multi-gigabit domain with a small footprint. At the same time it provides outstanding error correction performance, resulting in a low energy consumption and increasing range of wireless transmission. Its unique pipeline architecture can be customized at design-time to deliver best performance on any target technology (ASIC technology nodes and FPGAs). Insertion, removal and balancing of pipeline stages within the IP core is flexible and allows for optimization of required routing resources, path delays between pipeline stages, throughput, and footprint at the same time.
